Hello Farhana, I just tried version 1.4 and a recent (12/28) daily build of version 1.5, both Mac Aqua, and did not have this problem. When you have a problem, it is better to use "Help... Report a Bug" in the Chimera menu (instead of sending e-mail here) because the report automatically includes important information such as what version of Chimera you are using and what kind of computer. There will an area to type a description of the problem and to include your e-mail address if you are hoping for a reply. Sorry, we cannot offer advice unless we can reproduce the problem. I can only mention there are other ways to add the distance without double-clicking. For example, you can select the two atoms (Ctrl- click, Shift-Ctrl-click) and then use the command "distance sel" or the "Create" button on the Distances tool (under Tools... Structure Analysis) to add a distance monitor between the two selected atoms. At least on a Mac, you can also move molecules with the "finger mouse" by combining that with various keys, but it is not as easy as using the "real mouse." <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/mouse.html#2button> I hope this helps, Elaine ----- Elaine C.

Hello, I have been using Chimera for some months but suddenly my distance measurement is not working. I pick one atom and then shift-double pick the other atom, the hand shows, it blinks a couple times but no distance menu pops up. Any idea what could be wrong?! I just uninstalled and reinstalled the chimera software again, still the same trouble. [I use a laptop whose mouse works great (except when I need to move the molecules, then I use a real mouse instead of the laptop's finger mouse)]. Any help is greatly appreciated.
Thank you for your time. Farhana
